如何修复我的地图上有一个巨大的碰撞盒？

Question

我正在尝试制作一款游戏，我想要在我的岛屿上设置碰撞箱。我不明白为什么碰撞盒覆盖了我的 pygame 窗口的整个右侧！我正在学习 pygame 和 python，但我不知道该怎么做。我一开始就使用 ChatGPT 来帮助我。

这是我的代码。我尝试过调整代码大小，但只会让敌人（海军陆战队）和文本命中框让我立即死亡。如果有点模糊，我很抱歉，我是堆栈溢出的新手。

Answer 1

问题不是

HITBOX

而是

BORDER

在

if ... and ship.x + VEL + ship.width < BORDER.x:

您需要

WIDTH

而不是

BORDER.x

if ... and ship.x + VEL + ship.width < WIDTH:

---

顺便说一句：

pygame.Rect()

有许多有用的属性。

您可以使用

ship.right

代替

ship.x + ship.width

if ... and ship.right + VEL < WIDTH:

您可以使用

ship.bottom

代替

ship.y + ship.height

if ... and ship.bottom + VEL < HEIGHT:
